Performance Assessment of Superconducting Submillimeter-Wave Limb-Emission Sounder-2 (SMILES-2)
Paper in proceeding, 2019

© 2019 IEEE. SMILES2 is a mission prepared for the next call-for-proposals for JAXA/ISAS M-class scientific satellite mission. It aims at scanning the atmospheric limb from 20 to 160 km above the surface at frequencies near 700 GHz and 2 THz. It could provide the temperature and composition as well as, for the first time, the horizontal wind vector above 30 km, the atomic oxygen in its ground state above 90 km, and the atmospheric density and the geomagnetic field vector near the mesopause. The mission is proposed for the 2nd time and the instrument design has been improved for accounting for the recommendations of the review committee. In this publication, we discuss the measurement performances assessed from simulations including latest results showing the mission potential for measuring the geomagnetic field between 70-110 km.
